Group Activity Recognition by Using Effective Multiple Modality Relation Representation With Temporal-Spatial Attention

no code implementations • IEEE Access 2020 • Dezhong Xu, HENG FU, Lifang Wu, Meng Jian, Dong Wang, AND XU LIU

Then, we propose two types of inference models, opt-GRU and relation-GRU, which are used to encode the object relationship and motion representation effectively, and form the discriminative frame-level feature representation.
